Answer 1

- (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
{
        //Add a new body/atlas sprite at the touched location
        for( UITouch *touch in touches ) {

            CGPoint location = [touch locationInView: [touch view]];
            location = [[CCDirector sharedDirector] convertToGL: location];

            b2Vec2 locationWorld = b2Vec2(location.x/PTM_RATIO, location.y/PTM_RATIO);

            CCSprite *mist=[CCSprite spriteWithFile:@"bubble.png"];
            mist.position=ccp(location.x,location.y);

            [self addChild:mist];
        }
}

Answer 2

你需要注册touchdispatcher我认为......（[layer registerWithTouchDispatcher]）

[glView setMultipleTouchEnabled：YES]; （也许这需要刷卡）
